Abstract: Enhanced content data is supplied in association with a media selection. The enhanced content data is customized responsive to a user profile. The uncustomized enhanced content is stored as a data structure having levels of nodes. Each node within a given level represents an alternative version of a shared enhanced content sub-topic. A processor chooses between nodes within the levels and assembles the chosen nodes to produce the customized enhanced content data.
